classic motorcycle forum

I hope I am posting to the right area and someone can help, my father in law is into his classic british bikes and has been offered an Ariel Square 4 - 1956, its a 4 piper, all as original including paintwork, original registration and log book, it does have some crome pitting on it though.

It runs but has not been restored.

The bloke wants £3,250 for it, is that a good price, what price do they go for restored?

Thanks for your help.
